Suspect : r599275 ?

From the CL above, assigning the issue to the concern owner 

@rbpotter - Could you please check whether this is caused with respect to your change, if not please help us in assigning it to the right owner.

Note : 
1. Provided suspect through 'Chromium bisect' script because unable to perform bisect using 'per-revision' bisect script.
2. Tried performing 'per revision' bisect on multiple Windows and Mac machines but unable to perform the same since getting "RuntimeError: We don't have enough builds to bisect." error.
3. Issue is not seen on Windows (7,8,8.1,10) and Linux (14.04 LTS)

Kindly review attached screen cast for same.

Thanks!
